First of all, I know that SLS made some, but none are what I'm after.
I'm hoping that someone meshing savvy will be willing to make a ccompetition carriage like this - with two seats (for driver and groom), and with shafts (for non-editing folks like myself). Doesn't need to be especially fancy.
Another carriage I'm after is this type of sulky, also with shafts.
I'd be EXTREMELY grateful if anyone made at least one of these! I'm in desperate need of these!
